Fasting during the month of Ramadan is one of the five pillars of Islam, which is of paramount significance. Fasting requires abstaining from food, drink, and sexual intercourse from dawn until sunset. The Prophet (peace and blessings be upon him) said, “Islam is built upon five pillars: testifying that there is no god except Allah and that Muhammad is the Messenger of Allah, performing Prayer, paying the zakah, making the pilgrimage to the Sacred House (Hajj), and fasting the month of Ramadan.” (Reported by Al-Bukhari and Muslim)

The eminent Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, states: “Intramuscular or intravenous injection in the daytime of Ramadan does not invalidate your fasting. If you find difficulty to do so in the daytime of fasting in Ramadan, you can go to the doctor at night after you break your fasting at sunset.”
